Abstract (en)

The invention relates to a converter (CVT) and a conversion method for converting an input data packet stream (IDPS) of consecutive data packets (DP0,0,DP1,0,DP2,0...DPN-1,0) each data packet including user (US0,US1,US2,...USN-1) data in the form of a predetermined number (Nsymbol0;Nsymbol1;NsymbolN-1) of consecutive data symbols from a plurality of N user channels (ch-0,...,ch-N-1), each user channel having a predetermined transmission rate TR0,TR1,TR2,...,TRn,...TRN-1, being defined as a basic transmission rate TRB or an integer multiple TRn=Kn<*>TRB thereof, into an output data symbol stream (ODSS) in which a respective number Kn of data symbols (S0,0(0);S1,0(0),S1,0(1),S1,0(2),S1,0(3); S2,0(0);...SN-1,0(0),SN-1,0(1)) of each data packet are sequentially arranged. The write means (W) writes the data symbols into a memory (M) in the row direction and a read means (R) reads the memory (M) in the column direction. Thus, independent of the transmission rate (TRB) of the individual user channels, a CDMA-modulator (MOD) can be provided respectively with the first data symbol or a set of first data symbols from each packet within a predetermined time interval (1/TRB). <IMAGE>
